ISO 10131-2:1997

Overview

ISO 10131-2:1997 specifies the test methods for assessing the safety of domestic foldaway beds. As part two of the ISO 10131 series, this international standard focuses on practical procedures to evaluate foldaway beds' safety performance, durability, and structural integrity under simulated normal and foreseeable abnormal use conditions. Intended for fully assembled beds, these test methods provide consistent and repeatable laboratory practices to ensure compliance with safety requirements in foldaway bed design and manufacturing.

Key Topics

• Scope and Applicability

  • Applies exclusively to domestic foldaway beds, excluding camp beds, sofa beds, and guest beds.
  • Tests to be conducted on beds fully assembled, following manufacturer instructions.
  • For beds with adjustable components, testing at extreme adjustment positions is required.

• Test Preparation

  • Conditioning the bed prior to testing to achieve full material strength, including storage under controlled temperature (23 ± 2 °C) and humidity (50 ± 5%) for at least one week conforming to ISO 554.
  • For glued components, a minimum of four weeks’ aging under normal conditions is recommended before testing.

• Test Equipment Requirements

  • Use of a 200 mm diameter rounded rigid load pad (patin de charge) with defined curvature to simulate applied forces accurately.
  • Test mattress specifications: polyurethane foam slab, 100 mm thick, density ~30 kg/m³, hardness per ISO 2439, dimensions covering at least 800 x 800 mm without exceeding bed base width.
  • Use of anti-slip stops on the floor surface to prevent bed movement during horizontal tests.

• Test Methods

  • Opening and Closing Force Measurement: Determining resistance forces during smooth bed operation with different mattress weights to assess ease of use and safety.
  • Articulated Joint Durability: Repeatedly opening and closing the bed to evaluate joint resistance and mechanical wear after 100 and 10,000 cycles.
  • Load Resistance and Durability Testing: Applying repeated vertical loads (1,000 N, 10,000 cycles) on critical points to assess structural integrity.
  • Horizontal Force Resistance: Applying lateral loads to test bed stability and resistance to tipping or displacement.
  • Unexpected Closure and Opening Tests: Assessing mechanisms against sudden movement forces to prevent injuries or accidental bed collapse.
  • Anchorage Strength: Verifying the strength and stability of bed mounting points under sustained force.

• Reporting Requirements
  Test reports must include bed descriptions, mattress weight range, test results, compliance affirmation with ISO 10131-1 safety requirements, any deviations from test methods, and testing laboratory details.

Applications

ISO 10131-2 test methods serve multiple stakeholders in the foldaway bed industry:

• Manufacturers use these test methods to validate product safety and durability during product development, ensuring compliance with international safety standards.
• Certification Bodies and Laboratories apply standardized testing to certify foldaway beds, guaranteeing consistent safety and performance assessments.
• Retailers and Consumers benefit from assurance that the foldaway beds meet established safety criteria, reducing injury risks associated with bed operation and use.

Related Standards

• ISO 10131-1:1997 - Foldaway beds - Safety requirements and tests - Part 1: Safety requirements. (Specifies performance criteria that test methods in Part 2 help verify.)
• ISO 554:1976 - Standard for conditioning and testing atmospheres, ensuring test reproducibility under controlled environmental conditions.
• ISO 2439 - Testing foam materials’ hardness: critical for defining test mattress properties used in load application.

Summary

ISO 10131-2:1997 offers a rigorous framework for testing the safety and reliability of foldaway beds used domestically. By specifying detailed test methods for mechanical endurance, load resistance, and operational safety, this standard ensures foldaway beds are designed and manufactured to minimize hazards during use. Manufacturers and testing bodies employing these procedures help protect consumers and improve product quality, aligning with global best practices in furniture safety and durability testing.
